CHARLES BADGER, OF EDGERTON, VISCONSIN, ASSIGNOR TO MELVILLE BADGER, OF

SAME PLACEY GRIST-MILL.

Specication of Letters Patent No. 28,434, dated May 22, 1860.

To all whom it may concern:

Be it known that I, CHARLES Banana, of Edgerton, in the county of Rock and State of Wisconsin, have invented a new and useful Machine or Mill for Grinding and Bolting Grain; and I do hereby declare that I know of no machine or grist-mill on which this is an improvement or could be regarded as such, except the ordinary grist-mills now in common use throughout the country, which are, as far as my knowledge extends, always permanent and have never been made portable and do not involve to any extent the peculiar principles hereinafter set forth; and I hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which is made a Vpart of this specification.

The nature of my invention consists in constructing a grinding mill in which geared machinery is firmly attached to a movable frame that is placed inside of the principal frame that supports the bed or stationary stone and hopper-and which movable frame sustains at the upper end of the vertical shaft the runner or upper stone, and which interior frame, gearing attached thereto, vertical shaft and runner, are elevated and lowered together whereby the stones are separated or brought nearer together to grind coarse Grne-and whereby the different parts of the gearing retain their relative position undisturbed by such depression and elevation, also in combining the gear for driving the runner with the gear for driving the bolt so as to save the intervention and expense of additional gear to drive the bolt, also in placing one gear wheel on the opposite side of the pinion on the vertical shaft from the gear that receives the power and communicates the power to the vertical shaft and runner, whereby the vertical shaft is kept from vibrating, and giving great stability and steadiness of motion to light machinery.

The annexed drawings are a perspective view of the entire machine and its several distinct parts, in which- A represents the longitudinal elevation of the entire machine with the front side presented.

b F represents the front side of the bolt 55 represents the curb which surrounds the bur stone within, over which 5 represents lthe hopper.

The power is designed to be applied by a knuckle, crank or wheel at 24, which is the extremity of an arbor or shaft, atthe other extremity of which is a bevel cog wheel, from which the power is continued, transmitted and accelerated by a small corresponding bevel wheel to an upright shaft, as represented in the frame work by 25 On the top of this upright shaft is properly fitted and secured the common bur grinding stone, after the manner of fitting in common mills.

IVheel 18 is fitted on the left extremity of the bolt-shaft, located, as ordinarily, in the bolt-box before specified. Motion is received from the bevel wheel on the upright shaft by a corresponding bevel wheel on shaft 21 at the other extremity of which is the small wheel 20 fitting the wheel 1S, to which wheel 18 is transmitted reduced motion for bolting. If found desirable, the main arbor or shaft 24 may be extended and made the same shaft as 21 through to the small wheel 20, in which wheel 23 will be dispensed with.

15 is spout to conduct meal from the curb into the bolt. 16 is a similar spout to conduct coarse meal and feed to a bag or box placed on platform 17 At the mouth of spouts 15 and 16 are fitted certain slides by the regulation of and adjustment of which meal can be conducted either into the bolt, or into a bag or box on platform 17 at the option of the miller.

B represents a flo-ur trough at the base of the bolt box constructed nearly in the usual manner.

The shafts 21 24 and 25 with their accompanying wheels, are permanently secured in a frame as seen in Fig. 27, which frame is capable of an easy upward or downward motion, sliding on rods 57. This motion is obtained for the purpose of raising or lowering the bur stone, fitted on the top of the center shaft secured therein, and thereby setting the stone for coarse or fine grinding. This is done by means of the lever 29 the rod 30, the nut and screws 32 and the wheel 33 For the purpose of more perfectly securing the upright shaft 25 from an upward motion in case of high speed, a shoulder is made on said shaft to bear against the middle beam passing through the upper part of said frame work, specified in Fig. 27, which shoulder is more clearly represented in Fig. 59.

When the frame work is raised or lowered to any great extent, for the purpose of graduating the quality of the grinding, so that there is any danger of throwing the bolt wheel 18 out of gear, the bolt wheel 18 can be raised or lowered to fit the small wheel 20 secured in the frame work, by means of different sized wedges fitted in the mortseabove or below, through which the lever or beam passes on which the bolt shaft rests.

The peculiar usefulness and advantages of this grist mill are represented as follows, to wit: First, any kind of power can be applied to it, such as horsepower, steam or water power, or power obtained from windmills. Second, power is applied, by this peculiar construction, for the purpose of grinding in the most simple and feasible manner, and with but very little friction. Third, the peculiar and comprehensive construction of this mill by which the appropriate parts are brought into immediate contact and the whole machine, being a complete grinding and bolting mill, is reduced to the least possible space. Fourth, the cheapness with which this grist mill, combining and comprehending all the advanages of any grist mill, can be built. Fifth,

the small amount of power required to overcome the friction in this mill andto produce motion sufficient for grinding and bolting. Sixth, its adaptation to the wants of all classes, in that the larger sizes can be used thereof. This mill is intended however moreV particularly to supply the wants of the dry land towns of the west, by being made portable and worked by horse power. The smaller sizes are designed and calculated to be operated by a two horse power.

What I claim as my invention and desire to secure by Letters Patent is:

1. The frame work 27, in which the gearing is located, in combination with the vertical shaft and runner when arranged substantially as described and for the purposes set forth.

2. The combination of the devices for driving the runner, with the devices for driving the bolt when constructed and operated substantially as described.

3. The cog gears on each side of the pinion, in combination with the pinion and shaft in Fig. 27, substantially as described and for the purpose set forth.
